Be sure to dress very well and be prepared to act like a celebrity when you arrive at the Tân Sơn Nhất international airport (SGN) in Sài Gòn. In the picture below, you see the crowd that greets you after you clear passport control, baggage pickup, and customs, and then step out into the main lobby from the door on the right to find transportation.
You might as well step out with your hands raised in triumph since everyone will be staring at you from the spectator gallery lining the "runway" to local transportation. You will certainly be judged on the appropriateness and fashion sense of your clothes and luggage.
I realize that most international airports have areas like this for people waiting for relatives to arrive out of customs, but I have seen none quite as staged as this. It is quite endearing to see Vietnamese families united once again as overseas Vietnamese arrive back into "the old country".
